New! Semi-Annual Enterprise (Preview) Version 2408
Version 2408 has now also been released to the Semi-Annual Enterprise Channel (Preview). Although it doesn’t contain any new features for Outlook, there is one for Word that is Outlook related. It also contains over 40 fixes related to Outlook. Some highlights are;
- Assign Tasks (Word)
You can facilitate collaboration and stay organized by creating and assigning tasks directly from within your Word document using @mentions in comments. The people you assign the tasks to will receive email notifications, letting them know they need to take action. Ready to give it a try? Open an existing document stored on OneDrive or SharePoint. Highlight the text that contains the information you want to comment on, select New Comment, write your comment and type @ followed by the name of the team member you want to tag. Then, press Ctrl + Enter to post your comment and select the Assign to check box to convert your comment into a task. - We added support for converting some COM add-ins to Web add-ins.
- We fixed an issue that caused users to see no prompt to send updates to attendees after removing attendees from a meeting on a shared calendar where the location of the meeting was set.
